ATTACHMENT FOR SHOE-LASTS.

Application filed January 8, 1917.

To all whom it may concern:

Be it known that I, HENRY F. LOEWER, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Attachments for Shoe-Lasts, of which the following is a specification.

The present invention relates to an attachment for shoe lasts to increase the forward bulge of the instep portion of the last so that the ordinary last for high shoes may be used for the manufacture of low shoes or pumps, it being necessary to make the instep portion higher in a low shoe than in a high shoe in order to obtain greater comfort. An object of this invention is to provide a construction which may be applied to the .last without perforating or otherwise injuring the same While, at the same time, providing for maintaining the attachment in the position to which it is ailiXed to the last.

To this and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter clescribed, the novel features being pointed out in the appended claims.

In the drawings Figure 1 is a side view of the last show ing the attachment mounted thereon and illustrated in section;

Fig. 2 is a view of the under side of the attachment Fig. 3 is a sectional view of the attachment on a line a-a, Fig. 2; and

Fig. 4 is a transverse sectional view on the line bb, Fig. 3.

Referring more particularly to the drawings, A indicates a last of any suitable construction designed for making high shoes. On the instep portion of the last, the attachment is mounted. This attachment comprises a bulge producing portion 1 which Specification of Letters Patent.

is thicker at the center and gradually becomes thinner toward its upper and lower edges. From opposite sides of this bulge producing portion 1 gripping devices 2 eX- tend in the form of arms integral with the bulge producing portion and deflected to one side of the latter, that is, the under side to produce a substantially U-shaped memher. The under side of the bulge producing portion 1 is preferably corrugated at 3, the corrugations extending transversely of -the longitudinal axis of the device. The attachment as a whole is preferably made from one piece of rubber, the arms 2 being separated by a distance which is slightly less than the width of the last at the instep so that, in applying the attachment to the last, it is necessary to force the arms 2 apart, after which they are freed and spring into gripping attachment with the opposite sides of the instep portion of the last, thus holding the attachment to the last. The corrugations on the under side of the bulge producing portion prevent the attachment from slipping downwardly on the instep portion of the last, and this is further prevented by the friction due to making the attachment of rubber.

What I claim as my invention and degripping arms on opposite sides of the bulge producing portion.

HENRY F. LOEWER.
